Abstract
Have a multi-sealed ball valve, comprise valve body and valve ball, be provided with valve seat in valve body, valve ball is arranged on valve seat, between valve seat and valve body, is provided with elastic seal ring, in the sealing surface of valve seat and valve ball, is filled with grease.Elastic seal ring is made up of the synthetic wear-resisting annulus of steel fiber of nanometer, or elastic seal ring is made up of flexible metal annulus.Elastic seal ring together with the utility model arranges between the valve body of ball valve and valve seat is filled with grease in the sealing surface of valve seat and valve ball valve seat and valve ball, has increased the sealability of ball valve.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to Fluid valve, and particularly a kind of have a multi-sealed ball valve.
Background technique:
Ball valve extensive use in fluid control, in fluid control application, the sealing of valve is even more important.In prior art, valve adopts one seal ring to be sealed conventionally, and sealing effect is not ideal enough; Repeatedly move at valve, after folding, seal ring easily weares and teares, aging etc., causes sealing effect bad, causes fluid leakage; Meanwhile, in multiple valves of connecting, if upstream valve leaks, also can cause certain influence to valve downstream in stream control.
Summary of the invention:
The purpose of this utility model is to provide a kind of multi-sealed ball valve that has, and described thisly have multi-sealed ball valve and will solve the undesirable technical problem of ball valve sealing effect in prior art.
This multi-sealed ball valve that has of the present utility model, comprises valve body and valve ball, in described valve body, is provided with valve seat, described valve ball is arranged on described valve seat, wherein, between described valve seat and valve body, be provided with elastic seal ring, in the sealing surface of valve seat and valve ball, be filled with grease.
Further, described elastic seal ring is made up of the synthetic wear-resisting annulus of steel fiber of nanometer.
Or described elastic seal ring is made up of flexible metal annulus.
The utility model and prior art are compared, and its effect is actively with obvious.Elastic seal ring together with the utility model arranges between the valve body of ball valve and valve seat is filled with grease in the sealing surface of valve seat and valve ball valve seat and valve ball, has increased the sealability of ball valve.
Brief description of the drawings:
Fig. 1 is the structural representation of multi-sealed ball valve from mid-sectional that have of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, of the present utility model have a multi-sealed ball valve, comprise valve body 1 and valve ball 3, in described valve body 1, be provided with valve seat 2, described valve ball 3 is arranged on described valve seat 2, wherein, between described valve seat 2 and valve body 1, be provided with elastic seal ring 4, in the sealing surface of valve seat 2 and valve ball 3, be filled with grease.
Further, described elastic seal ring 4 is made up of the synthetic wear-resisting annulus of steel fiber of nanometer.
Or described elastic seal ring 4 is made up of flexible metal annulus.
The working principle of the present embodiment is: elastic seal ring 4 together with being provided with between the valve body 1 of ball valve and valve seat 2, in the sealing surface of valve seat 2 and valve ball 3 valve seats 2 and valve ball 3, be filled with grease, and increase the sealability of ball valve.
